“…Unlike DEMO, which is designed to deliver the net electrical energy to the grid [3,9], DTT is an experimental plant, which means that its electrical power systems will be "simpler" than those expected for DEMO [10] and the nuclear requirements are less stringent [11]. Nevertheless, the power systems are not trivial in terms of size and complexity, especially in terms of power density [12][13][14]. In fact, all the main types of loads present in ITER (and maybe in DEMO) will be implemented in DTT [12,15,16]: Converter for superconducting and copper coils [14], electron cyclotron resonance heating (ECRH) [17], ion cyclotron resonance heating (ICRH) [18], negative neutral beam injector (NBI) [19], cryogenic and water cooling systems and so on [10,16].…”
